Application July 8, 1957, Serial No. 670,597

3 Claims. (Cl. 311-53) The present inventionv relates to shaving equipment and in particular to a complete razor, including both blade and support therefor, that can be provided at such low cost as to disposable after but a single use thereof.

The present application is a continuation in part of my application Serial No. 558,972, led January 13, 1956, which has matured into Patent No. 2,817,897,

A major object of the invention is to provide an efcient razor that is intended for temporary use, as when traveling or when temporarily and unexpectedly detained in a hospital or other institution.

Another object of the invention is to supply a disposable razor that can be included in a shaving kit for coin-machine vending or distributed free of charge by hospitals, jails or other institutions, the razor being constructed in such an economical manner that it `can be sold at a low price, or distributed at a very nominal price, or free, its cost being very nearly inconsequential.

A still further object of the invention is to furnish a disposable razor that is made very easily from a minimum number of parts and having a simple yet effective manner of securing the blade to the handle.

These and other objects and advantages of the invention will become apparent from the following description of a preferred form and certain variations thereof, and from the drawing illustrating those 'forms in which:

Figure 1 is a perspective view of said preferred form of my invention;

Figure 2 is an exploded perspective of the device shown in Figure 1, with parts thereof cut away to show details of its interior construction;

Figure 3 is a vertical cross-sectional view taken along the line 3-3 of Figure l;

Figure 4 is a partially cut-away perspective View of one variation of my disposable razor invention; and

Figure 5 is a partial perspective View, partially cut away, of a second variation of my invention.

Referring now to the drawing for the general arrangement of the invention and in particular to Figures 1 and 2, it will be seen that an elongate rigid frame member F and blade B constitute the razor R of the presently preferred form of my invention. It will be noted that the razor R is not of the safety-type, but rather resembles the straight razor, and its extremely low cost is, in part, attributable to this construction. As will be come apparent, even though razor R resembles the conventional straight razor, it nevertheless avoids the relatively higher cost of a rigid vhollow-ground blade, although that type of blade could be used, by providing means of supporting a wafer-thin blade with su'lcient rigidity to enable it to readily cut the users beard.

In order to keep the cost of razor R very low, it is preferred that frame member F be made of wood, although a strip of metal or plastic or other rigid material could be used for this purpose if desired. Frame member F is an elongate, substantially rectangular sheet of such material consisting of a handle portion and a Patented Dec. 8, 1959 ICC blade-holding portion 412 that is a linear extension of said handle portion.- Handle portion 10 is, of course, suliciently long to be conveniently grasped in the fingers for manipulation and may be provided with a rounded first end 14. The opposite sides 16 of frame member F are perfectly flat and the second end 18 of ysaid frame is straight.

Blade-holding portion 12 is best seen in Figure 2. An open-ended slot 20 is formed along the longitudinally extending centerline of portion 112, extending from straight end 18 thereof toward handle portion 10. Although not absolutely necessary, I prefer that slot 20 taper inwardly slightly, its Iwidth decreasing as it progresses toward handle portion 10. Blade-holding portion 12 being thus bifurcated by slot 20 is divided into two branches 22 between which a portion of the structure of a blade member B can be inserted.

Blade member B includes two blade arms 24 that are transversely spaced apart the same distance as the thickness of blade-holding portion 12 and to which arms a web 28 is axed, as by welding, to the inwardly facing surfaces thereof along the longitudinal center-lines of `arms 24. As can be seen in Figure 3, web 28 is substantially rectangular in cross-section and may, if desired, be formed with a taper to conform to the taper of slot 20` of blade-holding portion 12. Web 28 is of substantially the same length as slot 20 and is lfrictionally received therein, branches 22 of portion 1!2 being resiliently deformable to hold said web with a tight fit. When relatively thin blade material is used, it wil-l be found advisable to further secure blade B to frame F by means of pins 30 fastened transversely through blade member B and branches 22 of blade-holding portion 12. The inwardly facing surfaces of blade member B are then 'securely held in abutting relationship to at sides 16 of frame mem-ber F to be rigidly lsupported thereagainst so that when one of cutting edges 26 is used in shaving, in the manner of Figure 3 there will be no deection thereof. The manner of use of razor R is entirely conventional, as Figure 3 shows.

Figure 4 depicts a variation of my invention in which the frame member is not bifurcated, and in which two separate blades are provided, but which is otherwise the same as the form shown in Figures 1 to 3. rI'hus, the razor of Figure 4 includes a matched pair of blade members B, B' in contact with opposite sides 16 of frame member F, and retained in position by means of pins 30. Frame member F has a second end 18 which is straight and in which there is no slot. Blade member B, on the far side of vframe member F as vshown in the drawing, has a straight end 27 which projects slightly beyond end V13 of the frame member. Blade member B', which is partially cut away to provide a clear view of ends 18 and 27, has a similar projecting end 27', not shown. The manner of use of the razor of Figure 4 is the same as for the razor of Figures l to 3.

Figure 5 depicts a second variation of my invention which is generally the same as the form shown in Figures 1 to 3, except that the frame member is not bifur- `cated and the blade member is of a lesser width than the frame member. The manner of use of the razor of Figure 5 is slightly different in that frame member F is held so that one of its edges 32 rests on the skin of the user when a cutting edge is disposed in shaving engagement.

In Figures 4 and 5, parts which are the same as in Figures 1 to 3 are identified by the same reference characters.

Although the forms of the invention herein shown and described are fully capable of achieving the objects and providing the advantages hereinbefore mentioned, it is to be understood that they are merely illustrative of presently preferred embodiments thereof and that I do not mean to limit myself to the details of construction herein shown and described other than as defined in the appended claims.

I claim:

l. A disposable razor that comprises: a frame member formed of a rigid material, said member including an elongate handle and a blade-holding portion that extends therefrom; and a U-shaped member that defines two laterally separated, parallel blade arms that are wider than said portion and have longitudinally extending cutting edges provided thereon, with said blade-holding portion disposed between said arms and rigidly aliixed thereto.

2. A device as defined in claim 1 in which said frame member is of elongate rectangular configuration, with said blade-holding portion formed with an open-ended tapered slot that extends along the longitudinal centerline thereof and decreases in Width as it approaches said handle portion of said frame; and a web of substantially rectangular cross-section that extends between said blade arms and is rigidly affixed thereto along the longitudinal center lines thereof, said web being adapted to be frictionally received in said slot of said blade-holding portion to be securely held therein.

3. A device as defined in claim 2 characterized further by the fact that said device is provided with a plurality of pins extending transversely through said blade arms and handle portion to fasten them together.
